Strap for De Ville Co-Axial 37.5 Yellow Gold / Silver

The Omega De Ville 4631.31.31 has a strictly 16mm lug width. This dimension is the standard for De Ville watches from the 1990s generation and is specifically determined by the distance between the case lugs. Personal verification with a caliper is recommended to exclude any errors when searching for compatible straps.

Dark brown alligator is the natural choice to match the yellow gold case: the regular grain and deep color create an elegant contrast without excess. Alternatively, vegetable-tanned calf leather in cognac or burgundy offers superior artisanal patina, while black shell cordovan allows maximum versatility of use over time.

The procedure requires specific tools (spring bar tool) and precision in handling the case. Position the watch on a soft pad, locate the lug pins, gently release the internal spring with the spring bar tool and remove the old strap. Insert the new strap by perfectly aligning the holes before re-engaging the spring. If you lack experience, it is recommended to contact an official service center.

Yes, provided the strap is specifically dimensioned for 16mm lug width. Custom artisanal straps from Milano Straps are fully compatible and offer superior material quality compared to OEM straps. It is important to verify that the width does not exceed 16mm to ensure correct engagement with the case lugs.

The lifespan depends on the quality of the leather and maintenance. An alligator or shell cordovan strap, with proper care (avoiding excessive moisture and sweat), guarantees 4-7 years of daily use before requiring replacement. Vegetable-tanned calf leather, being softer, may need renewal after 3-5 years. Milano Straps offers an 18-month warranty on all custom straps, coverage that attests to the artisanal solidity of the craftsmanship.
